Anton [14]2 years ago

Answer:

See below ↓↓

Step-by-step explanation:

a₁ refers to the first term of the sequence.

That is clearly : a₁ = <u>6</u>

<u></u>

The formula for the nth term is :

  • aₙ = a₁rⁿ⁻¹
  • Common ratio (r) = quotient of consecutive terms
  • r = -12/6 = -2

Therefore, the nth term is :

  • aₙ = <u>6(-2)ⁿ⁻¹</u>

What is the slope of a line parallel to the line y=3x-4=8y+1
Lyrx [107]

Answer:  If the original equation is y = 3x -4,  the slope is 3.

Any equation of a line parallel to the line <u>y = 3x -4</u> will have a slope of 3.

Step-by-step explanation:

In slope-intercept form, y =mx + b the coefficient of x, m is the slope.

Here 3 is that value.

It is very unusual to have two equal signs in a question about slope.

I am not sure what to do with the <u><em>=8y + 1</em></u>

Is this supposed to be another equation in the system, missing a term?

<h2>The value of \sqrt{x}0.49x^{18} = 0.49x^{\dfrac{37}{2}}</h2>

Step-by-step explanation:

We have,

 \sqrt{x(0.49)}x^{18}

To find, the value of \sqrt{x(0.49)}x^{18} = ?

∴  \sqrt{x(0.49)}x^{18}

= 0.7x^{\dfrac{1}{2}} x^{18}

= 0.7x^{18+\dfrac{1}{2}}

Using the identity,

a^{m}.a^{n}=a^{m+n}

= 0.7x^{\dfrac{36+1}{2}}

= 0.7x^{\dfrac{37}{2}}

Thus, the value of \sqrt{x(0.49)}x^{18} = 0.49x^{\dfrac{37}{2}}
